High space heating mainly has convection heating, hot air heating, radiation heating several ways, in recent years, with the improvement of the national science and technology level of heating technology is also developing rapidly, commonly used heating methods, heating equipment have significantly changed. The use of convective heating in tall space buildings is generally only used as an auxiliary heating facility due to large temperature gradients and other problems. Due to the uniform temperature distribution of the radiation heating system itself, the energy saving effect is remarkable, the human body feels comfortable, and has the potential to save energy, more and more market attention. Gas infrared radiation heating is widely used. 
 
In the process of radiant heating, indoor air does not directly absorb radiant heat. Among them, gas radiation heating using natural gas, liquefied petroleum gas as the heat medium, due to the high thermal radiation temperature, so the human body receives more radiant heat, feel comfortable, the ground, equipment, and the surrounding walls absorb a lot of radiant heat temperature rise. The thermal comfort is obvious, and the energy saving effect is also remarkable. 
 
Gas radiant heating is a way for heating tall buildings, which can realize real-time control of zoning and sub-system, especially for intermittent heating buildings. When this method is used for heating, the temperature gradient in the indoor height direction is very small, and a more ideal thermal comfort environment can be created. At present, it has been widely used in industrial buildings such as industrial plants, hangars, vehicle maintenance warehouses, warehouses, logistics centers and other tall buildings. 
 

	According to the measured results, most of the heat is heated by radiation, and a small part of the heat is transferred to the indoor air in the form of convective heat transfer. Most of the heat will radiate in the heating space, radiation on the object, the human body. The rest of the radiant heat is absorbed by the ground and indoor equipment, when the temperature of the indoor equipment, the ground and the wall is higher than the indoor air temperature, the heat will exist in the form of convective heat transfer.

Gas infrared radiation system installation requirements in the design should ensure that the entire system for negative pressure operation mode, no leakage of heating space, no open flame burning. IMPRESIND gas infrared radiation equipment promoted and sold by Beijing Leadway Power Co., LTD., does not need to install external combustion equipment, and independent heaters are generally installed in the upper part of the building heating space, which does not occupy the building space. 
 
IMPRESIND gas infrared radiation heating system burns natural gas, and the hot fluid generated flows in the radiation tube under the drive of the smoke exhaust fan (vacuum pump), and the high temperature surface of the radiation tube stimulates the far infrared radiation wave. After the heat exchange of the hot fluid inside the radiation tube, part of the product will be recycled through the premix chamber, and the other part will be discharged by the smoke exhaust fan. Secondary heating to achieve energy saving, environmental protection, high efficiency, reduce operating costs. Overall, in a heating season, gas radiation heating can save 30%-50% energy than traditional convection heating.
